I have had a constant problem with wet front passenger floorboards. Rain or shine, hot or cold, AC on or off, I can't find the problem. I have checked from time to time and have no issues then check again and the fabric and the under liner is very wet.

Has anyone else come accross this issue?

 

Yeah. Its condensate from the AC usually, but there is a grommet under the edge of the carpet next to where the floorpan meets the firewall. Check it and make sure its sealed.

 

CHECK HEATER CORE THAT IS WHAT HAPPENS WHEN CORE STARTS LEAKING USUALLY NOT ENOUGH THAT U WILL NOTICE COOLANT LEVAL LOW DO U SMEEL A SWEET LIKE SMELL INSIDE VEHICLE ANOTHER GOOD INDICAROR OF HEATER CORE LEAK

 

Thanks to both....

I have cheked the overflow for the condensate under the hood. Seems OK. Others have told me to blow itout with air. My follow up question would be how is this condensate forming when it has not been hot here?

I will look into the grommet next.

David,

It is not the heater core. I does not have that sweet smell like you describe.

 

I agree with the others here. I would guess it to be a clogged drain hose from the AC.

 

I have found that keeping the windows up while in car washes helps. Sorry, I couldn't resist.

My driver side floor board stays soaked and I don't know why! My carpet is now orange and molded (cleaning doesn't help I've tried) So it's completely ruined from the constant wetness. 😣
